Answer:

absence of body cavity.....

Answer 2

In contrast to Annelids, the Platyhelmenthis shown is :

(a) Absence of body cavity

• Platyhelmenrhis do not have the body cavity because they are acoelomates.

• Annelids have a fluid-filled body cavity called coelom that's why these are called eucoelomates.

• Platyhelminthes are flat because of the absence of coelom. They are invertebrates.

• Platyhelminthes are flatworms they have only mouth and longitudinal muscles.

• For example, tapeworms and flukes.
